综合物探在寿阳煤矿水害探测中的应用

利用瞬变电磁法和环形测深相结合的综合勘探方法,对煤矿富水区域进行探测。瞬变电磁法施工方便,该方法对低阻含水体特别灵敏,受体积效应影响小,分辨率高,从平面上控制富水区域大小。环形测深可以探测不同方向的岩层视电阻率变化情况,对于地下径流方向进行控制。2种方法相结合,即平面控制区域,含水区域延伸变化情况也得到控制。对于富水区域的探测,使用综合勘探,可以减少单一方法多解性问题,使探测结果更符合实际,这2种方法相结合的理论,有助于今后这方面的探测研究。

Application of Comprehensive Geophysical Exploration in Water Disaster Dtection in Shouyang Coal Mine

By using transient electromagnetic method and loopshaped sounding method, comprehensive exploration has been carried out in waterrich area in coal mine. Transient electromagnetic method is convenient in construction. It is particularly sensitive to low resistance containing water, and affected by the volume effect lowly with high resolution. It will control the scope of waterrich area from plane. Loopshaped sounding can detect the apparent resistivity change of strata in different direction, and control the groundwater flow direction. Combination of two methods can control the area from plane, and control regional water extension. For the detection in waterrich area, the use of comprehensive geophysical exploration can make the detection more accordance with the actual results. Combination of the two methods can help detecttion research in this area in the future.
